What Is Dissolved Oxygen in Hydroponics

Introduction to DO in Hydroponics

Dissolved oxygen, or DO, is an important element in hydroponics. It refers to the oxygen that gets mixed into the nutrient solution your plants rely on.

Why is this so crucial? Well, just like we need air to breathe, plants need oxygen for their growth and health. When the DO levels are ideal—between 6 to 8 mg/L—plants thrive. But if the levels drop below 5 mg/L, it can stress them out and slow down their growth.

On the flip side, having higher levels of DO can be a game-changer. It helps plants absorb nutrients more quickly, which means their roots grow stronger. This makes them more resilient and better able to fight off diseases.

To keep those DO levels where they need to be, consider using aeration techniques. Options like air stones or pumps can help mix oxygen into the nutrient solution effectively.

Dissolved oxygen (DO) is essential for successful hydroponic gardening. It ensures better nutrient absorption, prevents root diseases, and promotes healthy plant growth. Learn how to maintain optimal DO levels and keep your plants thriving.
